"It's really unbelievable the amount of things that can just be completely made up," the 26-year-old actress told the talk show host. "And it's really frustrating," she added in reference to rumors she and Rivera didn't get along on set of the hit Fox musical series.

However, the actress made light of the conversation, joking: "For me, if there were ever really a cat fight on the show, you'd know about it because I'd get a ring, and I'd put Jell-O in it, and I would make it fun for everyone and it would be super hot."
